* mov: handle h263 and flv1 for codec_tag 'H','2','6','3'Janne Grunau2012-12-19
| | | | | | | | | | The sample in https://bugzilla.libav.org/show_bug.cgi?id=393 and samples/F4V/H263_NM_f.mp4 both have codec_tag H263 for different codecs. H263 is apparently used by Flash Media Server for Sorensen Spark videos. Patch based on commit 5442083b1c541dd166b3adf39131259fc846a62b by Carl Eugen Hoyos. Fixes bug 393.
* mov: validate number of DataReferenceBox entries against box sizeJanne Grunau2012-12-07
| | | | | Avoids a 2G memory allocation and parsing of random data in mov_read_dref(). The fuzzed sample sample.mp4_s224424 triggers this.
* mov: compute avg_frame_rate only if duration is knownJanne Grunau2012-12-07
| | | | Fixes an assert in fuzzed sample sample.mp4_s265930.
* lavf: add a common function for selecting a pcm codec from parametersJustin Ruggles2012-11-28

* Include libavutil/channel_layout.h instead of libavutil/audioconvert.hJustin Ruggles2012-11-11
| | | | Also reorder some other #include when applicable.
* mov: support random access point groupingYusuke Nakamura2012-09-19
| | | | | | | | | Frames described by this grouping are the starter of a closed or an open GOP. This is useful for open GOP of H.264 stream which is not described by sync sample atom. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mov: check for EOF in long lasting loopsLuca Barbato2012-09-18
| | | | | | | A quite widespread pattern in the demuxer is read a 32bit unsigned integer and then loop till this value is reached. Checking for EOF prevents pathological situations.
* mov: stsd entries must be at least 16 byteMichael Niedermayer2012-09-16
| | | | | | | | | | Fix near infinite loop in stsd parsing. Bug found by: Diana Elena Muscalu The size is unsigned according the specification. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* lavf: deprecate r_frame_rate.Anton Khirnov2012-07-29
| | | | | | | | | | | | | | | | | | | | According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.

* mov: enable parsing for VC-1.Anton Khirnov2012-05-18
| | | | | This makes lavf discard broken timestamps for non-B frames in samples/isom/vc1-wmapro.ism.

| | | | fixes Bug 225
* movdec: Don't parse all fragments if ignidx is setMartin Storsjö2012-02-22
| | | | | | | | | | In nonseekable files, we already stop parsing the toplevel atoms after finding moov and one mdat. In large seekable files (or files that are seekable, but slowly, e.g. http), reading all the fragments at the start can take a considerable amount of time. This allows opting out from this behaviour. Signed-off-by: Martin Storsjö <martin@martin.st>
* movdec: Restart parsing root-level atoms at the right spotMartin Storsjö2012-02-22
| | | | | | | | | | | If parsing moov+mdat in a non-seekable file, we currently abort parsing directly after parsing the header of the mdat atom. If we want to continue parsing later (if looking to parse later fragments), we need to skip past the content of the mdat atom, otherwise we end up parsing the content of the mdat atom as root level atoms.

* movdec: Adjust keyframe flagging in fragmented filesMartin Storsjö2012-02-21
| | | | | | | | | | | | | | For video, mark the first sample in a trun which doesn't have the sample-is-non-sync-sample flag set as a keyframe. In particular, the "sample does not depend on other samples" flag isn't enough to make it a keyframe, since later frames still can reference frames prior to that one (the flag only says that that particular frame doesn't depend on other frames). This fixes bug 215. Signed-off-by: Martin Storsjö <martin@martin.st>
